Split Seal Ring Joint Structure for Oil Leakage Resistance

The patent applies local quality by providing abutment surfaces with specific multi-stage inclined structures only at the split portions of the seal ring, while the rest of the seal ring maintains a simple annular structure. This localized complexity enhances sealing performance at the critical split interfaces without requiring the entire apparatus to be complex.

The seal ring is segmented into multiple parts by splitting it circumferentially, with abutment surfaces provided at the split portions. This segmentation allows the seal ring to be assembled in a divided state and then joined together, improving sealing performance at the junctions through the multi-stage inclined abutment surfaces while maintaining overall structural simplicity.

The seal ring is divided into multiple segments that can be separated circumferentially, allowing easy removal and replacement without disassembling the entire apparatus. The segments are joined through abutment surfaces with multi-stage inclined structures that ensure reliable sealing at the split interfaces, thus maintaining sealing performance despite the segmented structure.

The abutment surfaces utilize multi-stage inclined structures in the radial direction to achieve reliable sealing at the split interfaces. By adding dimensional complexity in the radial direction (multiple inclined stages) rather than requiring complex circumferential features, the patent maintains sealing performance while preserving the ease of replacement benefit from the split structure.
